Functionality
The Set-reset function (SRMEMORYQT) is a flip-flop with memory that can set or
reset an output from two inputs respectively. Each SRMEMORYQT function block
has two outputs, where one is inverted. The memory setting controls if the flip-flop
after a power interruption will return the state it had before or if it will be reset.
SRMEMORYQT propagates quality and time as well as value.
